Schneider contactor current suppression module function

The function of Schneider contactor current suppression module is to suppress the peak high voltage generated by the reverse potential of the coil when the contactor is disconnected. When the contactor coil is disconnected, the electromagnetic energy stored in the magnetic current loop will be released when the coil is closed, and it will be recovered by overvoltage wave, resulting in steep slope and extremely high amplitude, which can reach kilovolts. This situation seriously interferes with electronic equipment, causing insulation burning and damaging sensitive devices. The function of Schneider contactor current suppression module is to suppress the peak high voltage generated by the reverse potential of the coil at the moment when the contactor is disconnected, and effectively protect the circuit sensitive to' high frequency' interference.
